PHP应用技巧小总结：几个有用的小技巧

1、关于PHP重定向

方法一：header("Location: index.php");
方法二：echo "";
方法三：echo "";

2、获取访问者浏览器

function browse_infor()
{
$browser="";$browserver="";
$Browsers =array("Lynx","MOSAIC","AOL","Opera","JAVA","MacWeb","WebExplorer","OmniWeb");
$Agent = $GLOBALS["HTTP_USER_AGENT"];
for ($i=0; $i{
if (strpos($Agent,$Browsers[$i]))
{
$browser = $Browsers[$i];
$browserver ="";
}
}
if (ereg("Mozilla",$Agent) && !ereg("MSIE",$Agent))
{
$temp =explode("(", $Agent); $Part=$temp[0];
$temp =explode("/", $Part); $browserver=$temp[1];
$temp =explode(" ",$browserver); $browserver=$temp[0];
$browserver =preg_replace("/([\d\.]+)/","\1",$browserver);
$browserver = " $browserver";
$browser = "Netscape Navigator";
}
if (ereg("Mozilla",$Agent) && ereg("Opera",$Agent))
{
$temp =explode("(", $Agent); $Part=$temp[1];
$temp =explode(")", $Part); $browserver=$temp[1];
$temp =explode(" ",$browserver);$browserver=$temp[2];
$browserver =preg_replace("/([\d\.]+)/","\1",$browserver);
$browserver = " $browserver";
$browser = "Opera";
}
if (ereg("Mozilla",$Agent) && ereg("MSIE",$Agent))
{
$temp = explode("(", $Agent); $Part=$temp[1];
$temp = explode(";",$Part); $Part=$temp[1];
$temp = explode(" ",$Part);$browserver=$temp[2];
$browserver =preg_replace("/([\d\.]+)/","\1",$browserver);
$browserver = " $browserver";
$browser = "Internet Explorer";
}
if ($browser!="")
{
$browseinfo = "$browser$browserver";
}
else
{
$browseinfo = "Unknown";
}
return $browseinfo;
}
//调用方法$browser=browseinfo() ;直接返回结果

3、获取访问者操作系统

function osinfo() {
$os="";
$Agent = $GLOBALS["HTTP_USER_AGENT"];
if (eregi('win',$Agent) && strpos($Agent, '95')) {
$os="Windows 95";
}
elseif (eregi('win 9x',$Agent) && strpos($Agent, '4.90')) {
$os="Windows ME";
}
elseif (eregi('win',$Agent) && ereg('98',$Agent)) {
$os="Windows 98";
}
elseif (eregi('win',$Agent) && eregi('nt 5\.0',$Agent)) {
$os="Windows 2000";
}
elseif (eregi('win',$Agent) && eregi('nt',$Agent)) {
$os="Windows NT";
}
elseif (eregi('win',$Agent) && eregi('nt 5\.1',$Agent)) {
$os="Windows XP";
}
elseif (eregi('win',$Agent) && ereg('32',$Agent)) {
$os="Windows 32";
}
elseif (eregi('linux',$Agent)) {
$os="Linux";
}
elseif (eregi('unix',$Agent)) {
$os="Unix";
}
elseif (eregi('sun',$Agent) && eregi('os',$Agent)) {
$os="SunOS";
}
elseif (eregi('ibm',$Agent) && eregi('os',$Agent)) {
$os="IBM OS/2";
}
elseif (eregi('Mac',$Agent) && eregi('PC',$Agent)) {
$os="Macintosh";
}
elseif (eregi('PowerPC',$Agent)) {
$os="PowerPC";
}
elseif (eregi('AIX',$Agent)) {
$os="AIX";
}
elseif (eregi('HPUX',$Agent)) {
$os="HPUX";
}
elseif (eregi('NetBSD',$Agent)) {
$os="NetBSD";
}
elseif (eregi('BSD',$Agent)) {
$os="BSD";
}
elseif (ereg('OSF1',$Agent)) {
$os="OSF1";
}
elseif (ereg('IRIX',$Agent)) {
$os="IRIX";
}
elseif (eregi('FreeBSD',$Agent)) {
$os="FreeBSD";
}
if ($os=='') $os = "Unknown";
return $os;
}
//调用方法$os=os_infor() ;

4、文件格式类

5、php生成excel文档

header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:filename=test.xls");
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
?>

//改动相应文件头就可以输出.doc .xls等文件格式了
